Product Q&A

Q:How to select a control valve for fluctuating pressure?

In HVAC or high-rise systems with pressure instability, use a Self-Operated Differential Pressure Control Valve or Proportional Control Valve. These function without external power, managing the main valve via pilot guide to prevent over-pressure, ensuring equipment safety.

Q:What is the best way to prevent water hammer in fire protection systems?

Fire pumps cause surge on startup, risking pipe bursts. Use Multi-Functional Pump Control Valve or Water Hammer Arrestor Valve to adjust opening/closing speeds, dissipate energy, and protect Fire Pump Rooms from hydraulic shock.

Q:Are solenoid control valves durable enough for high-frequency drainage automation?

Traditional solenoid valves face coil burnout or seal wear with frequent use. Zentif's Solenoid Control Valves have a diaphragm design, reducing friction and enhancing response. Their corrosion-resistant seals ensure bubble-tight performance in sewage or industrial wastewater, extending maintenance intervals.

Q:How to solve thermal imbalance in HVAC chilled water systems?

Thermal imbalance stems from static hydraulic deviation. Install a Dynamic Balancing Electric Control Valve or Proportional Integral Electric Two-Way Valve. These valves adjust flow based on real-time load needs, maintaining constant flow despite pressure changes, eliminating hot/cold spots, and enhancing energy efficiency.

Q:What materials are available for the valve body?

We offer customized flange standards and material options including Ductile Iron, Cast Steel, and Stainless Steel to meet project-specific requirements in different regions.
